    <h4 class="sectiontitle">现象描述</h4>
    <p>执行RMAN备份操作时，备份任务长时间没有进度，且安装客户端的主机操作系统及内核版本为Redhat7.6 3.10.0-957.el7.x86_64。</p>
   </div>
   <div class="section">
    <h4 class="sectiontitle">可能原因</h4>
    <p>Redhat7.6 3.10.0-957.el7.x86_64版本内核问题导致<span>本产品</span>进程重启，进而导致备份存储上文件系统不可写，备份任务卡住。</p>
   </div>
   <div class="section">
    <h4 class="sectiontitle">处理步骤</h4>
    <ol>
     <li><span>使用PuTTY，登录已安装客户端的主机。</span></li>
     <li><span>执行以下命令查看主机操作系统及内核版本是否为Redhat7.6 3.10.0-957.el7.x86_64。</span><p></p><p><strong>cat /etc/redhat-release</strong></p> <p><strong>uname -r</strong></p>
      <ul>
       <li>是，执行<a href="#oracle_gud_0138__li3304144725013">3</a>。</li>
       <li>否，联系技术支持协助处理。</li>
      </ul> <p></p></li>

     <li><span>将下载到的内核包上传至数据库主机。</span></li>
     <li><span>执行以下命令安装内核包。</span><p></p><p><strong>rpm -ivh </strong><em>内核包</em></p>
      <div class="p">
       以kernel-3.10.0-957.10.1.el7.x86_64.rpm为例，如：
       <pre class="screen">rpm -ivh kernel-3.10.0-957.10.1.el7.x86_64.rpm</pre>
      </div> <p></p></li>
     <li><span>重启操作系统后，再次执行以下命令查看内核版本是否为新安装的版本。</span><p></p><p><strong>uname -r</strong></p> <p></p></li>
